You have ADHD, Mr Clarkson is your English teacher—his aware of your ADHD

Its currently lunchtime and you are pasting up and down the corridors— singing to yourself, playing with your keys

You keep walking along quite happily, your not paying any attention to your surroundings— you then walk straight into Mr Clarkson, this is like the 100th time you’ve walked into him

He looks down sympathetically. He makes sure your okay

“Your lucky it’s me you’ve walked into- if it was Mr Budgen, he wouldn’t have been happy. Why don’t you come sit down in my office for a little bit?”
